So in my personal point of view I see Satoshi's first attempt to solve the centralized trust issue with a decentralized ledger called now blockchain but then for micropayments we found it's vulnerabilities and we call them scaling issues. So my hope is, in the 10th anniversary of Bitcoin we can retake his original idea and now with the research and advance of the decentralized systems we can found a better way to accomplish it's main idea.
I know it's just matter of time Bitcoin will solve all it's issues and reach the adoption and awareness it deserves all across the world

I don't know exactly what the purpose of Satoshi is to create bitcoin, maybe you are right that Satoshi wants to rebel the existing monetary system. I think Satoshi also understands the problem of trust and scalability in advance. Trust about bitcoin can be answered when Satoshi doesn't exist, but he forgets to renew scalability, even though when bitcoin experienced hardfork and gave birth to BCH that had a block size bigger than bitcoin, they still remained loyal to bitcoin. Maybe in the future, i think Satoshi will give birth to a more perfect new technology later, even though he doesn't call me Satoshi. I know it's just matter of time Bitcoin will solve all it's issues and reach the adoption and awareness it deserves all across the world
